Tenebre
(Anchor Bay, 1982)

When an American murder-mystery novelist journeys to Rome on a European promotional tour, he discovers a psychopath is replicating the brutal murders from his latest book. Even worse, the beleaguered author is getting pinned with the rap and receiving death threats. Italian director Dario Argento is known for supernatural chillers like Suspiria and Phenomena, but he’s also adept at ­Hitchcock-esque thrillers like this one, which keeps you guessing until its blood-soaked denouement.

Tombs of the Blind Dead (Blue Underground, 1971)

When a young woman abandons her boyfriend and a girlfriend after a fight by jumping off a train going through rustic Spain, she wanders aimlessly to an old castle, only to become hunted by the infamous Knights Templar, who have been resurrected as sightless, skeletal zombies who ride on horseback and hunt down their victims by sound. Amando de Ossorio’s haunting film is part of a deluxe box set and available separately online.
